A statement from Lancashire Fire and Rescue Service last night said: "When crews arrived they found the incident involved nine vehicles.

"Firefighters used holmatro cutting equipment, small tools and portable lighting equipment. Several casualties were assessed and treated by paramedics at the scene and there was one casualty conveyed to hospital via ambulance.

"The motorway will remain closed until the carriageways can be cleared and surface gritted. Firefighters were in attendance approximately one hour."
